- the viscosities are 2,700 and 3,400 mPas at 190 ° C.
- the tensile strength decreases by at least 20% if the ratio changes to 50 to 50 parts by weight at the expense of the poly- ⁇ -olefin becomes.
- the addition of waxes is used, among other things, to fine-tune the viscosity and to reduce stringing. In most cases, polybutenes with a lower molecular weight are recommended as plasticizers. It is cheaper to use paraffinic or naphthenic mineral oils.
- the recommended formulation for sprayable hot melt adhesives for hygiene articles contains 70 parts Vestoplast 704 (a poly- ⁇ -olefin), 25 parts Escorez 5380 (a hydrogenated polycyclopentadiene), 5 parts Napvis D 10 (a polybutene which is liquid at room temperature) and 0.4 parts Irganox 1010 (an antioxidant for polyolefins).

- the first-mentioned process involves atomizing the melt into fine droplets of melt, while in "spin spraying" a melt thread swirls out of the spray can and, without tearing, is deposited in a spiral path on the substrate to be coated.
- the spray technology generally permits contactless application and the coating of uneven, irregular surfaces It is still suitable for applications where, on the one hand, a flat adhesive is desired, but on the other hand it is required that the bonded layer is permeable to air or moisture material can be saved. Another advantage is that the coating is more sensitive to temperature Substrates. Due to the contactless application and due to the very low heat content of the incoming melt or the melt thread, the substrate is stressed or damaged far less than with conventional application technologies.
- the hotmelt spray technology is environmentally friendly and covers a total of many applications that were previously reserved for the sprayed solvent-based adhesives.
- the good sprayability naturally relates both to the “atomizing” mentioned above and to “spin spraying”.
- spin spraying For a uniform spray pattern produced by spin spraying, a viscosity of the mass to be sprayed which is largely independent of the shear rate is required at the respective application temperature. If this were not the case, one would not be able to achieve a constant spray width, for example, with intermittent spraying processes. Both at the beginning and at the end of the respective spray cycle, the viscosity would then be increased due to the lower shear rate and the spray pattern would consequently change.
- the spraying behavior is characterized in particular by the following properties: a) Temperature fluctuations between 140 and 160 ° C affect the adhesive values only to an extent of + 14%, based on an application weight of 4 g / m 2 . b) Fluctuations in the application weight within 2 to 4 g / m 2 affect the adhesive values only in the range of + 7%. c) The application methods such as control coat or spin spray have only a minor influence on the adhesive values, namely + 6%.

- the nonwovens can be mechanically consolidated by needling, stitching or by Swirling using sharp water jets (so-called spunlaced fleeces).
